Specification of Letters Patent.

Patented April 3, 1906.

Application filed February 25, 1903- Serial No. 144,962.

To a whmn it may concern:

Be it known that I, LoUIs ZoTI UE POU- LIOT, shade manufacturer, of thecity of Montreal, Province of Quebec, Canada, have invented a certainnew Improvement in Pulleys for Window-Shade Rollers; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

My invention relates to pulleys for windowshade rollers by which theshade can be conveniently raised or lowered without liability of injuryto the shade and without disturbing the adjustment thereof.

A further object is to provide a device for the purpose stated which issimple in construction, eifective in operation, and which can be easilyand quickly applied to the shaderoller.

To these ends the invention consists in a device adapted to be appliedto the end of the roller of a shade, constructed and arrangedsubstantially as hereinafter illustrated and described, and defined inthe appended claim.

Referring to the drawings, in which similar letters of referenceindicate similar parts, Figure 1 is a view in perspective of awindowshade provided with a device constructed in accordance with thisinvention. Fig. 2 is a side view of the supporting-bracket. Fig. 3 is aperspective of one of the disks. Fig. 4 is a detail showing the twodisks and cooperating parts in position on the shade. Fig. 5 isasectional View showing the disks and securingpin. Fig. 6 is a detail ofthe guide-plate.

In the drawings, A represents the roller-bar of any ordinary orpreferred form of springoperated window-shade. At one end of saidroller-bar is secured a pair of metal disks a a circular in form andspaced a suitable distance apart by means of an intervening axis or huba the same being attached to the roller by means of a pin b, one end ofwhich projects beyond the outer end of the disk at and which passesthrough the hub and both disks. Upon the disk (1 is formed an attachingpoint or orifice to which the operating-cord O is attached. In operationthe cord 0 is attached to one of the disks a a and wound about the hubor axis a By pulling on the cord O the shade can be wound or unwound inthe wellknown manner.

A guide-plate B is secured in any suitable manner, preferably to thesupporting-bracket B, and is provided with a guide-slot b, through whichthe operating-cord O is passed and by which it is retained in operativepositi( n.

In operating this invention it is .iy necessary to properly adjust thetension of the spring in the roller to the weight of the shade, thendraw down the shade to its lowest limit, attach the cord O to itsfastening-point, and wrap two or three turns about the hub. The shademay then be run up to any desired point by simply pulling upon the cord.

'le a simple and effective type of this invention is disclosed herein,it is to be understood that many changes in the details may be madewithout departing from the scope of the invention.

What I do claim as my invention, and desire to secure by Letters Patent,is

In a device of the character described the combination of ashade-roller, a pulley comprising a pair of disks held spaced apart byan intermediate hub and secured to said roller, a supporting-bracketremovably connected to the roller and having a base to engage a fixture,and a guide member to be removably secured to the supporting-bracketthrough the medium of the means for securing said bracket to thefixture, said guide member being coextensive in width with the width ofthe pulley and formed with a longitudinal opening practicallycoextensive in width with the width of the hub.
